[Bug 1847822] Re: CephFS authorize fails with unknown cap type

[Billy Olsen]

** Patch added: "bionic patch"
   https://bugs.launchpad.net/cloud-archive/+bug/1847822/+attachment/5296864/+files/dont-validate-fs-caps-on-authorize.patch

** Description changed:

+ [Impact]
+ 
  Attempting to provide access to a user within Ceph to a specific mount
  path fails with unknown cap type. This appears to be due to the monitor
  not knowing how to validate the caps that are provided with the mount
  path per upstream bug https://tracker.ceph.com/issues/39395 and
  subsequent pull requests.
  
  This is fixed in Mimic (13.1.0+) and included in the current Luminous
  devel release (upcoming 12.2.13).
  
+ 
+ [Test Case]
  
  Steps to recreate:
  
  1. Install ceph w/ ceph-fs.
  
  2. Mount ceph filesystem and create subdirectory for restricting access
  $ ceph-fuse -k /etc/ceph/ceph.client.foo.keyring --id foo -m 10.5.0.5:6789 /mnt/ceph-fs
  $ mkdir /mnt/ceph-fs/bar
  
  3. Authorize access for ceph user to rw a directory
  $ ceph fs authorize ceph-fs client.foo /bar rw
  
  Expected Results:
  
  The authorize command to succeed
  
  Actual Results:
  
  Error EINVAL: unknown cap type '/bar'
  
- Upstream pull-request:
- https://github.com/ceph/ceph/pull/28666
+ [Regression Potential]
+ 
+ Regression potential is low as this has already been fixed upstream and
+ has seen additional testing without additional problem reports from the
+ change. The change does affect the validation of capabilities, so if a
+ problem were to arise it would likely be in the verification of
+ capabilities when the code is parsing.
